Road marking removal machine using high pressure water jetting road sign or airfied rubber.Present removal work for road markings has been time-consuming and labor intensive because it has been performed manually using shaving type equipment.
The traditional process causes traffic delay due to the passing control, resulting in unexpected accidents to workers working at dangerous road circumstance. Besides, the current shaving method leads to air pollution as well as explosive accidents caused by propane gas.
Thus, we have studied to develop the automatic removing equipment which consists of a high pressure water-jet system, automatic control system and mobile system: the water-jet system consists of an intensifier and nozzles to give a high pressure and spray on the marking;
The automatic control system is composed of one axis robot using a hydraulic servo actuator controlled by a lever; and the mobile system employs a truck which plays an important role for transport of equipment and forward movement in a removal process.
Traditional methods of road marking removal
Traditionally, road markings were removed through the process of burning. This is not only time-consuming, but dangerous through the release of smoke and fumes.
This method involves an industrial tool that exerts high temperatures to burn off the existing markings. Due to this hazardous process, there has been a need for an alternative method of road marking removal.
In this paper, we have analyzed the characteristics of road markings and investigated current removing methods in this field. In addition, we have organized and designed automatic removing equipment.
Road markings are laid onto roads with the intention of being permanent, and so the removal of them can be tricky. Old road markings have become a standard feature on roads, sometimes causing confusion to drivers.
Because of this, it is extremely important to have a method that effectively removes road markings, whilst doing so in a safe way to workers.
Water jetting road marking removal
Using water jets, the removal of road markings can be quick, easy, and efficient. Whether the road markings are red, white, yellow, or more, using a top of the range electronically controlled machine can remove the markings through propelling itself backwards and forwards.
This process does not involve any harsh chemicals or abrasives.Water jets can be used for the removal of road markings on a variety of surfaces, such as standard roads, airport runways and markings on school grounds.
Highway markings road marking removal machine introduced water blasting as a road marking removal equipment. It is now the preferred road marking removal technique by authorities .
Water blasting quickly removes markings faster and more thoroughly than abrasive methods – without damaging the pavement or asphalt. Water blasting is fast and productive, and avoids exposing the environment to chemicals or contaminants. It also simplifies clean up, is dustless and leaves a clean surface.
Water blasting uses high pressure by an extremely powerful motor/pump to clean and remove markings from the pavement surface. These powerful motors can deliver pressure at the cleaning head of up to 40,000psi (2,758bar).
Advantages of using hydro blasting for road marking removal
- No chemicals, additives or abrasive materials are used
- No fumes, smoke or dust is generated
- Noise levels are considerably lower than alternative road marking removal techniques
- Suitable for use on all types of road surfacing materials
- Operates with traffic flow
- No personnel required to work on the carriageway
- Self contained unit complete with debris vacuum recovery
- Minimal surface impact
Fault self diagnostic technology for road marking removal machine
- Continually monitors more than 20 aspects of the system during operation. Faults are displayed on the monitor. Review of the detected faults can reduce troubleshooting time by 70%.Coordinated Section Operation
- The boom can be rapidly and accurately repositioned by coordinating the movement the first and second sections
Max safety technology for the road marking removal machine
- Pump Overload Protection Technology
Relief valves are mounted on the boom cylinder counterbalance valves. These valves will release pressure in the event of excessive boom load to prevent damage to the boom.
- Hopper Screen Interlock Technology
As an operator protection measure, the pump will automatically stop when the hopper screen is opened.
- Hydraulic Oil Level Monitoring
The oil level in the hydraulic reservoir is continually monitored. If the level drops below a preset level, an alarm will sound and the pump will be stopped to prevent damage to the hydraulic system.
Control panel for the road sign rubber removal machine
- USA made control system ensure the high stability of the flow rate and continuous water jetting and guarantee high volumetric efficiencies at high pressures in a quick speed as well .
- It features for waterproof and dustproof ,the protection level reached to IP 65. Combining pump anti vibration technology ,the pump anti vibration technology reduces vibration during pumping by 50% allowing less movement and greater control of the end hose
